Baylor's Nathaniel Ezekiel just missed the podium in the 400mH but set a national record for his home country of Nigeria.

American Rai Benjamin pulled away for the world title, was briefly DQ'd as he clipped the final hurdle and they ruled it interfered with Ezekiel's hurdle but he was reinstated after video review.

World record holder Karsten Warholm faded down the stretch to finish 5th.
